PLX SM-AFR Serial upgrade

Please can somebody point me towards the guide for setting up the analog 5v pids for plx wb's, specifically how to program the V2 aswell ?

Thankyou.

Connect 1st PLX to AD1+ signal and AD1- ground.
Connect 2nd PLX to AD2+ signal and AD2- ground.
Log the pids EXT.AD1 and EXT.AD2.
Select the calc pids CALC.AFR_PLX1/2 and CALC.BEN_PLX1/2.

In FVS2 device settings, checkmark the box to always include External Analog Pids.

Thanks Joe, think it worked out ok, although more fumbling than knowing what I'm doing



I had to remove some odd pids that it did'nt like, maybe that's because I still have the HPtuners 2bar custom tune loaded,
but at least I am slightly further forward. I can't see the BEN pids...are they to convert the voltage to the AFR ?
I have boost via plx and fuel pressure via aeroforce 150psi sensor to set up next.

On the PIDs tab, look at the right-hand column, it is titled "Parameter", click on the title (the word "Parameter") to sort alphabetically on that column...

then look down that column until you see the pids CALC.BEN_PLX1 and CALC.BEN_PLX2...

the BEN pids are the correction multiplier, to see their definition do rightclick->More Info on each of them (on the PIDs tab).



Summary: the AFR pids convert voltage to AFR; the BEN pids calculate the correction multiplier (to apply to your VE or MAF tables).
